Abstract
【解決手段】基本添加間隔を設定したときの基本排気温度に対する現在の排気温度の変化量に基づいて、その排気温度の変化量が大きいほど、燃料の添加間隔を短くするように補正する(ステップST1〜ST4)。このような添加間隔の補正により、高地などにおいて排気温度が上昇したときには、その排気温度上昇に応じて燃料の添加間隔が短縮補正され、燃料の添加量が増量補正されるので、燃料添加弁の先端部の温度上昇を抑制することができ、これによって燃料添加弁の噴孔がデポジットにて閉塞されるという問題を回避することができる。
【選択図】図3
Description
本発明の燃料添加装置を適用するディーゼルエンジンの概略構成を図1を参照して説明する。
エンジン1の各部位には、各種センサが取り付けられており、それぞれの部位の環境条件や、エンジン1の運転状態に関する信号を出力する。
ECU100は、図2に示すように、CPU101、ROM102、RAM103及びバックアップRAM104などを備えている。ROM102は、各種制御プログラムや、それら各種制御プログラムを実行する際に参照されるマップ等が記憶されている。CPU101は、ROM102に記憶された各種制御プログラムやマップに基づいて各種の演算処理を実行する。また、RAM103は、CPU101での演算結果や各センサから入力されたデータ等を一時的に記憶するメモリであり、バックアップRAM104は、例えばエンジン1の停止時にその保存すべきデータ等を記憶する不揮発性のメモリである。
まず、ECU100は、DPNR触媒4bへのPMの堆積量を推定している。PM堆積量を推定する方法としては、例えば、エンジン1の運転状態(例えば、排気温度、燃料噴射量、エンジン回転数等)に応じたPM付着量を予め実験等により求めてマップ化しておき、このマップにより求められるPM付着量を積算してPMの堆積量とする方法や、車両走行距離もしくは走行時間に応じてPMの堆積量を推定する方法、あるいは、触媒装置4にDPNR触媒4bの上流側圧力と下流側圧力との差圧を検出する差圧センサを設け、そのセンサ出力に基づいてDPNR触媒4bに捕集されたPMの堆積量を推定する方法などが挙げられる。
まず、上記したように、高地等でのエンジン運転状態では、吸入空気量が平地よりも減少するため排気温度が上昇する。このように環境変化(大気圧変化)により排気温度が上昇した場合、予め設定された設定添加間隔に基づく詰り防止添加制御では、燃料添加弁25の先端温度を所定値(デポジットの生成を抑制できる温度)以下に保つことができなくなる場合があり、燃料添加弁の噴孔閉塞が発生する可能性がある。これを解消するため、この実施形態では、詰り防止添加制御を実行する際に、大気圧の変化による排気温度の変化に応じて燃料の添加間隔を補正して燃料添加弁25の先端部の温度上昇を抑制する点に特徴がある。
以上の例では、基本添加間隔Tbに排気温補正係数βを乗じて燃料の添加量を補正しているが、これに替えて、1回当たり基本添加時間(図7参照)に排気温補正係数を乗じて燃料の添加量を増量補正するようにしてもよい。なお、1回当たり基本添加時間を補正する場合、排気温補正係数は、排気温度変化量ΔThが大きくなるほど大きな値となるように設定する。
